Now, the actor/director's family has filed a lawsuit for a wrongful death against the surgeon and hospital that treated Paxton.
The Twister and Apollo 13 actor's wife, children, and his estate filed the suit in a Los Angeles Superior Court last week against Cedars-Sinai Medical Center and cardiovascular surgeon Ali Khoynezhad, alleging negligence on their part.
In the lawsuit, Paxton's family accuses Khoynezhad of carrying out an improper procedure that caused complications that ultimately resulted in the actor's death last February 25, while also blaming the hospital for its inactivity.
The wrongful death lawsuit not only alleges that the doctor who spearheaded the heart surgery used risky methods, but also that Bill Paxton's death was preventable. The 61-year-old actor had undergone heart surgery at the Cedars-Sinai Medical Center just 11 days before his death.

Also taking aim at Seoul, Trump complained that America's 2012 free trade deal with South Korea "was a disaster". Several lawmakers cited the need to maintain USA energy independence and the electrical grid.
The document says that Paxton suffered multiple complications and that Khoynezhad was not in the operating room ("and based upon information and belief, not in the hospital") when the actor began suffering the complications. Symptoms of heart valve damage often don't appear until many years after recovery from rheumatic fever.
The USC report added that Paxton's surgery likely resulted in something getting loosened up and traveling to the brain or a blood clot forming and traveling to the brain. Paxton's cause of death was officially determined to be a stroke.
The lawsuit claims Cedars-Sinai "misrepresented and/or concealed information relating to the risks of surgery and care that would be provided and/or failed to adequately explain the proposed treatment or procedure".
According to Bill Paxton's death certificate, he suffered the stroke and died after the surgery left him with cardiogenic shock, excessive bleeding and compromised his aorta. And that "continuous care and coverage" was not provided during the time that the doctor was away from the patient.
